Abstract (en)
[origin: EP2703890A1] An electrophotographic photosensitive member in which a leakage hardly occurs, a process cartridge and electrophotographic apparatus having the electrophotographic photosensitive member, and a method for producing the electrophotographic photosensitive member are provided. The conductive layer in the electrophotographic photosensitive member contains metal oxide particle coated with tin oxide doped with niobium or tantalum. The relations: Ia ¤ 6,000 and 10 ¤ Ib are satisfied. The conductive layer before the test is performed has a volume resistivity of not less than 1.0 × 10 8 © ·cm and not more than 5.0 × 10 12 ©· cm.
